A relativly big RLC PDU that was still sent with the good CQI in a big grant now needs to be split across many tiny segments because the CQI degraded so much. The retx couting for each transmitted segment caused the retx counter to reach maxRetx quickly. With this patch we do not increment the retx counter for each transmitted PDU or segment of a PDU but instead only increment the counter when a given SN is added to the retx queue. This can happen either: a) if the SN is negativly acknowledged and was not already on the retx queue, b) no new data is available for tx and a SN is selected for retx. This is in accordance with TS 36.322 which handles retx counting in section 5.2.1 according to the above description. --- lib/src/rlc/rlc_am_lte.cc | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/lib/src/rlc/rlc_am_lte.cc b/lib/src/rlc/rlc_am_lte.cc index 6cc8ab07a..b5d691137 100644 --- a/lib/src/rlc/rlc_am_lte.cc +++ b/lib/src/rlc/rlc_am_lte.cc @@ -608,6 +608,11 @@ void rlc_am_lte::rlc_am_lte_tx::retransmit_pdu(uint32_t sn) // select first PDU in tx window for retransmission rlc_amd_tx_pdu& pdu = tx_window[sn];
